Does anyone here use Output Buffering?

Just curious, because I make these little CMS systems and it might be great to avoid "header already sent..." errors.
Right now I just use best practices to avoid those errors, does this work well?

just code the right way and you error's are gone

Yes, I use output buffering, but not to avoid the "headers already sent" problem: I use output buffering to compress the page, for reduced bandwidth usage and faster download, as I described in my recent blog entry: http://www.justsoftwaresolutions.co.uk/webdesign/reduce-bandwidth-by-compressing-pages.html

100% right

If you are using output buffering for compression is ok. If you use it to stop seeing "Headers already sent" errors then you just wasting memory.
